Answer:
a = -14
Step-by-step explanation:
f(a) = -43
3a - 1 = -43
3a = -43 + 1
3a = -42
a = -42/3
a = -14

Answer:
55.4 ft²
Step-by-step explanation:
The special triangle with angles 30°-60°-90° has side lengths in the ratios ...
1 : √3 : 2
The area of the triangle can be found using the area formula ...
A = 1/2bh
where b is the base and h is the perpendicular height.
__
<h3>sides</h3>
The longest side is given as 16 ft. This corresponds to "2" in the ratio, so the other two sides have lengths ...
8 ft, 8√3 ft
__
<h3>area</h3>
These area the perpendicular sides of the triangle so, work well to find the area.
A = 1/2bh
A = 1/2(8√3 ft)(8 ft) = 32√3 ft²
A ≈ 55.4 ft²
The area of the triangle is about 55.4 square feet.
Flipping something over to the Y axis is as simple and making the X vaules their opposite. (Negatives to positives and visa versa)
